A graphing calculator is a calculator with the capability of graphing an equation on a built-in coordinate grid on the screen. They usually have a simple LCD grid screen, and by typing in the equation (e.g., 5x+3), the screen refreshes to display a graph of the equation in a set window range.
A Texas Instruments graphing calculator can be used as a basic calculator, a scientific calculator and a graphing calculator.
Graphing calculator was created in 1985.
Graph the equation then find the x intercepts.
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
A graphing calculator is a scientific calculator with a graphing display window. Otherwise, there are no limits to the type of calculations that can be made on either of them.
On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.
Usually a graphing calculator should have all the capabilities you expect from a scientific calculator (and more, since it does the graphing). For more details, check the manual of your calculator if you already have one.
Someone can find a free online graphing calculator at Meta-Calculator. On Meta-Calculator one can find graphing, scientific, matrix, statistics, and programmer's calculators.
Here is a great site that will tell you everything you know about graphing calculator programming, and its got programs there to! See the related link, "Graphing Calculator Programming".
use a graphing calculator. chances are, it's not linear; it's probably got some high-degree function with non-whole number coefficients. i think you can download a free graphing calculator online.
Texas Instruments TI-84 Plus Graphing Calculator is a reasonably priced, good graphing calculator.
